304/316L Polished Stainless Steel Sanitary 90° Welded Elbow - Corrosion-Resistant for Industrial Piping Systems

Food-grade stainless steel elbows are used to change the flow direction in sanitary piping systems while maintaining stable flow and high hygiene standards. Manufactured from 304 or 316L food-grade stainless steel, the inner surface is precision-polished to achieve low roughness, reducing residue buildup and preventing bacterial growth. The elbows are formed through bending or welded-polish fabrication, ensuring smooth curvature and seamless integration with sanitary pipelines.

In terms of performance, these elbows provide excellent pressure resistance and corrosion protection. Their smooth interior reduces fluid resistance, and all dimensions and materials conform to GOST/ISO hygiene and safety standards. Weld ends undergo solution treatment and internal–external polishing, ensuring a stable weld pool, minimal contamination risk, and strong structural integrity. The material retains toughness under low-temperature conditions and withstands frequent CIP/SIP cleaning processes.

Food-grade elbows are widely used in milk, beverage, brewery, purified water, juice concentrate, and pharmaceutical fluid lines. They are applied in food factories, pharmaceutical plants, cold-chain systems, brewing equipment, and other sanitary transport environments.

We supply both standard-stock sizes and customized options for bending radius, angle, and polishing grade. Flexible lead times are available, along with complete documentation such as material certificates, surface roughness reports, and sanitary compliance certificates to ensure smooth installation and reliable long-term operation.
